Local News in Brief : Gas Found in Sump Tests

January 24, 1988

Tests of soil, ground water and air at the Gardena Sumps by the state Department of Health Services have found low levels of hydrogen sulfide gas and other petroleum-related materials, but at levels that are not hazardous, officials said.

A report released this month revealed that the results of the August, 1987, tests were similar to results of testing in 1982, when low levels of lead, benzene and toluene were detected at the site, said project manager Dennis Leonard. The hydrogen sulfide gas was detected in the air after holes were bored 9 feet into the ground, he said.

The sumps, at the southwest corner of Artesia Boulevard and Normandie Avenue, were filled with waste from oil refining from 1930 to 1950.

Testing of soil around the site and monitoring of the air continues, officials said. The site is near land where the city plans to build a 40,000-square-foot medical and professional office building and another parcel purchased from Caltrans and slated for commercial use by developer Alexander Haagen.
